Physochlaina is a small genus of herbaceous perennial flowering plants belonging to the nightshade family, Solanaceae, found principally in the north-western provinces of China (and regions adjoining these in the Himalaya and Central Asia) although one species occurs in Western Asia, while others occur in Siberia, Mongolia and the Chinese autonomous region of Inner Mongolia. Some sources maintain that the widespread species P. physaloides is found also in Japan, but the species is not recorded as being native in one of the few English-language floras of the country. The genus has medicinal value, being rich in tropane alkaloids, and is also of ornamental value, three species having been gro…

Optimized ultrasound extraction and cytotoxic activity against HeLa cervical cancer cells of total flavonoids of Physochlaina physaloides (L.) G. Don. Introduction Physochlaina physaloides (L.) G. Don is a traditionally used botanical drug whose antitumor activity has been linked to flavonoid-enriched fractions. This study aimed to optimize the ultrasound-assisted extraction (UAE) of total flavonoids from the roots of P. physaloides and to evaluate the cytotoxic activity of the resulting optimized flavonoid extract (OFE) in human cervical cancer cells. Methods Total flavonoids were prepared from the roots of P. physaloides using UAE. A Box–Behnken response-surface design was employed to opt…

Hyoscyameae is an Old World tribe of the subfamily Solanoideae of the flowering plant family Solanaceae. It comprises seven genera: Anisodus, Atropa, Atropanthe, Hyoscyamus, Physochlaina, Przewalskia and Scopolia. The genera Atropanthe and Przewalskia are monotypic, the first being endemic to China and the second to Tibet. All seven genera of the tribe are poisonous and have a long tradition of use as medicinal plants, being rich in tropane alkaloids with anticholinergic properties. Furthermore, the genera Atropa, Hyoscyamus, Scopolia and Physochlaina have furnished entheogens - the first three in the historical context of European witchcraft and, more specifically, of the flying ointments…
